* Makefile.am (EXTRA_DIST): Add them.
(bin_SCRIPTS, MOSTLYCLEANFILES): Add gunzip, zcat, zcmp, zdgrep, zfgrep.
(.in): Use GZIP_BINDIR as the location of gzip binaries, if it is set.
(check-local): Use GZIP_BINDIR.
(install-exec-hook, remove-installed-links): Make 'uncompress' an
alias for gunzip.
* gzexe.1: At least one arg is required. Don't give cat as an
example, since gzexe refuses to compress cat due to a bootstrapping
issue. List more utilities in this category.
* gzexe.in, zdiff.in, zforce.in, zgrep.in, zless.in, zmore.in, znew.in:
Report our name in usage.
* gzexe.in: Don't compress bash. Don't use rmdir, so it's
OK to compress rmdir.
* gzip.c: Now requires that you compile with -DGNU_STANDARD=0 to
get non GNU-standard behavior. We now build with GNU-standard
behavior by default, so that programs do not depend on the names
of their executables.
* zdiff.in: Don't depend on the name of the executable, as per
GNU standard. Instead, rely on an internal --__cmp option.
Support ' in options. Check for failures in subsidiary gzip
invocations.
* zgrep.1: Clarify compression issues.
* zgrep.in: Don't assume POSIX-style case syntax. Remove unused var
have_optarg.
* zless.1: zless sets LESSMETACHARS now.
